This book, now in its second, completely revised and updated edition, offers a critical approach to the challenging interpretation of the latest research data obtained using functional neuroimaging in whiplash injury. Such a comprehensive guide to recent and current international research in the field is more necessary than ever, given that the confusion regarding the condition and the medicolegal discussions surrounding it have increased further despite the publication of much literature on the subject. In recent decades especially the functional imaging methods – such as single-photon emission tomography, positron emission tomography, functional MRI, and hybrid techniques – have demonstrated a variety of significant brain alterations. Functional Neuroimaging in Whiplash Injury - New Approaches covers all aspects, including the imaging tools themselves, the various methods of image analysis, different atlas systems, and diagnostic and clinical aspects. The book will help physicians, patients and their relatives and friends, and others to understand this condition as a disease.
In this paper pathophysiological interrelated deactivation/activation phenomena are set out in the example of whiplash injury. These phenomena could have been underestimated in previous positron emission tomography studies as their focus was on hypoperfusion rather than hyperperfusion. In addition, statistical parametric mapping analysis of cerebral studies is normally not fine-tuned to special interesting areas rather than to obvious clusters of difference.
Hatte Maria einen Jodmangel?
(2019)
Auch wenn sie im Internet-Zeitalter zu einer Normalität werden, bleiben Ferndiagnosen unter Medizinern umstritten. Erst recht vorsichtig sollte man sein, wenn es sich bei dem Patienten um die leibliche Mutter Gottes handelt. Doch wenn man in diesem Gemälde eine authentische Dokumentation sieht, ist der Befund eindeutig: Maria hatte zum Zeitpunkt der Geburt ihres berühmten Sohns auffällig lange und schlanke Finger sowie eine Struma des Grads II bis III.

Kommentar zum Artikel "Arthur Willis Goodspeed" von Otto Glasser, veröffentlicht in Science Vol. 98, Issue 2540, Seite 219 (doi.org/10.1126/science.98.2536.125).
Im Archiv für Kriminologie wurden bislang drei Arbeiten zur 3-D-CAD-Rekonstruktion der ersten "Eisernen Hand" des berühmten Reichsritters Gottfried ("Götz") von Berlichingen (1480-1562) vorgestellt. Mittlerweile sind einige neue Gesichtspunkte herausgearbeitet worden, die hier kurz als Ergänzung mitgeteilt werden sollen.
Method for controlling a device, in particular, a prosthetic hand or a robotic arm (US20200327705A1)
(2020)
A method for controlling a device, in particular a prosthetic hand or a robotic arm, includes using an operator-mounted camera to detect at least one marker positioned on or in relation to the device. Starting from the detection of the at least one marker, a predefined movement of the operator together with the camera is detected and is used to trigger a corresponding action of the device. The predefined movement of the operator is detected in the form of a line of sight by means of camera tracking. A system for controlling a device, in particular a prosthetic hand or a robotic arm, includes a pair of AR glasses adapted to detect the at least one marker and to detect the predefined movement of the operator.
Diese Arbeit beschäftigt sich mit der Biomechanik der Halswirbelsäule (HWS) beim Umgang mit dem Smartphone. Die Kräfte, die auf Wirbelkörper, Wirbelgelenke, Bandscheiben, Muskeln und Bänder wirken, werden mit steigendem Flexionswinkel der HWS größer. Die Beschwerden hingegen, welche der Smartphone-Nacken hervorruft, sind meist akut und mit regelmäßiger Bewegung und der Stärkung der Nackenmuskulatur gut zu behandeln. Eine Therapie ist somit auch zur Vorbeugung geeignet. Doch die Langzeitauswirkungen sind nicht außer Acht zu lassen, denn durch die steigenden Nutzungsmöglichkeiten der Smartphones steigt auch der durchschnittliche tägliche Gebrauch stärker an. So wird vor allem die tägliche Bildschirmzeit bei Jugendlichen immer länger. Das aktuell noch akute Krankheitsbild des Smartphone-Nackens, das nur selten einen chronischen Verlauf nimmt und Langzeitschäden verursacht, könnte sich durch fehlende oder zu späte Maßnahmen zu einem größeren chronischen Krankheitsbild entwickeln.
Knight Götz von Berlichingen (1480–1562) lost his right hand distal to the wrist due to a cannon ball splinter injury in 1504 in the Landshut War of Succession at the age of 24. Early on, Götz commissioned a gunsmith to build the first “Iron Hand,” in which the artificial thumb and two finger blocks could be moved in their basic joints by a spring mechanism and released by a push button. Some years later, probably around 1530, a second “Iron Hand” was built, in which the fingers could be moved passively in all joints. In this review, the 3D computer-aided design (CAD) reconstructions and 3D multi-material polymer replica printings of the first “Iron hand“, which were developed in the last few years at Offenburg University, are presented. Even by today’s standards, the first “Iron Hand”—as could be shown in the replicas—demonstrates sophisticated mechanics and well thought-out functionality and still offers inspiration and food for discussion when it comes to the question of an artificial prosthetic replacement for a hand. It is also outlined how some of the ideas of this mechanical passive prosthesis can be translated into a modern motorized active prosthetic hand by using simple, commercially available electronic components.
